style="font-size:16px;">蝶閥又叫翻板閥，是一種結(jié)構(gòu)簡(jiǎn)單的調(diào)節(jié)閥，同時(shí)也可用于低壓管道介質(zhì)的開關(guān)控制。蝶閥是指關(guān)閉件（閥瓣或蝶板）為圓盤，圍繞閥軸旋轉(zhuǎn)來達(dá)到開啟與關(guān)閉的一種閥，在管道上主要起切斷和節(jié)流作用。蝶閥啟閉件是一個(gè)圓盤形的蝶板，在閥體內(nèi)繞其自身的軸線旋轉(zhuǎn)，從而達(dá)到啟閉或調(diào)節(jié)的目的。蝶閥適用于發(fā)生爐、煤氣、天然氣、液化石油氣、城市煤氣、冷熱空氣、化工冶煉和發(fā)電環(huán)保等工程系統(tǒng)中輸送各種腐蝕性、非腐蝕性流體介質(zhì)的管道上，用于調(diào)節(jié)和截?cái)嘟橘|(zhì)的流動(dòng)。蝶閥所適用的場(chǎng)合蝶閥適用于流量調(diào)節(jié)。由于蝶閥在管路中的壓力損失比較**約是閘閥的三倍，因此在選擇蝶閥時(shí)，應(yīng)充分考慮管路系統(tǒng)受壓力損失的影響，還應(yīng)考慮關(guān)閉時(shí)蝶板承受管道介質(zhì)壓力的堅(jiān)固性。此外，還必須考慮在高溫下彈</span><span
